Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sweat-absorbing cap and a cap which are excellent in releasing heat and steam.

[0002]

2. Description of the Related Art Most of conventional head bodies and hats have a structure in which a band of synthetic leather is simply attached to the inner periphery of the head band portion, in particular, in which the user feels discomfort due to sweating.
In such a cap, since the synthetic leather does not absorb the sweat, the sweat stays in the head band or dries, and naturally, not only discomfort but also the work efficiency is reduced, The reality is that there is no countermeasure.

[0003]

However, when wearing a hat outdoors in the summer, sweating is more intense than expected, so that not only the operation of continuously wiping the sweat is required, but also the paper and There is a risk that the working tools and the like will be soiled and the working efficiency will be extremely reduced.

In order to prevent such a phenomenon, it is sufficient to add a cooling device. However, currently available cooling devices are too large or heavy, and are too practical for personal use. Was not.

[0005] In view of the current situation, it has been required to apply a material having a long lasting sweat-absorbing property and good air-permeability to a part of a head band that is in contact with the head of a cap body actually worn. .

The present invention has been made in view of the background of the prior art.
It is an object of the present invention to provide a sweat-absorbing cap and a hat excellent in breathability and sweat-absorbing property, paying attention to the transpiration and release of sweat.

[0007]

The present invention employs the following means in order to solve the above-mentioned problems. That is, in the sweat-absorbing cap body of the present invention, the constituent material of the interior material attached to the inside of the cap body is a water-absorbent cloth-like material having a water permeability / diffusion ability test front / back area ratio of 1.0 or more, and a porosity of 50%. % Or more of a breathable material. Further, the hat of the present invention is characterized in that such a sweat-absorbing cap is attached.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, it is extremely important that sweat, transpiration and release are efficiently carried out, especially in order to treat liquid sweat which sweats violently from the head. As a result of intensive research, we tried to intervene a specific interior material and found that this problem could be solved at once.

[0009] The interior material of the present invention comprises a water-absorbent cloth-like material having a front-to-back area ratio of water permeability and diffusivity test of 1.0 or more and a breathable material having a porosity of 50% or more. The former water-absorbent cloth-like material preferably has a knitting structure as shown in FIG. 1, for example, and is composed of a yarn 1 forming a knitting structure serving as such a cloth layer and a yarn 2 forming a mesh structure on the opposite surface. It is more preferable to use one in which the hanging yarn 2 in which the fibers are erected in a loop shape is present on one side or both sides of the fabric-like material.

As a typical example of the latter breathable material having a porosity of 50% or more, a double raschel knitted fabric having a honeycomb structure as shown in FIG. 2 is preferably used.

Hereinafter, the present invention will be described with reference to the drawings.

FIG. 3 is an overall view of a summer hat to which the sweat-absorbing cap of the present invention is attached. FIG. 4 is a sectional view taken along the line AA.

Here, reference numeral 3 denotes a thin knitted fabric serving as a top portion, and reference numeral 4 denotes a water impermeable sheet for preventing the fabric from being stained with sweat. Reference numeral 5 denotes a mesh-shaped knitted fabric on a side portion, reference numeral 6 denotes an outer peripheral material of a headband portion, and reference numeral 6 denotes a water-absorbent fabric which is a headband. Reference numeral 8 denotes a breathable material having a porosity of 50% or more, which functions as a space layer necessary for the water-absorbent fabric to evaporate the sweat absorbed. 9
Is a synthetic resin net which is a starting aggregate for the side portion.

On the other hand, a typical hat currently used, as shown in FIG. 5, uses synthetic leather having no water absorbency at the head band portion, and has a φ3 hole in the starting aggregate. A resin plate having a pitch of 30 mm is used. Naturally, this hat does not have the function to absorb the sweat that blows out harder than the head, and it cannot be said that it has the ability to discharge enough steam.

In contrast to such a conventional hat, the sweat-absorbing cap of the present invention is a cap that can be worn comfortably without sweat dripping even in summer and with improved steam discharge. is there. In other words, for the treatment of sweat that continuously blows out, the material composition of the headband part is important, but simply installing an absorbent pad as in the conventional case immediately saturates itself, and thereafter becomes sticky. The feeling is only fostered.

Therefore, at the portion in contact with the head of the head band, the liquid which is excellent in sweat absorption as shown in FIG. 1 and which is the absorbed sweat moves to the surface opposite to the absorbing surface, A material having a function of diffusing as a large surface is preferable. As such a material, a water-absorbent cloth having a surface area ratio of water permeability and a diffusion ability test of 1.0 or more is used.

Here, the water permeability and diffusivity tests in the present invention are measured and calculated by the following methods. That is, 0.1 cc of an ink solution obtained by diluting commercially available ink with 2.0 times water was dropped on a glass plate, and the back of the knitted fabric (the non-diffusion surface in contact with the skin) as each sample was placed on the glass plate. On the side in contact with the ink liquid, after 60 seconds,
This time, the knitted fabric is moved onto another glass plate, and again left for 3 minutes. The diffusion area was measured from the ink stains on the front and back surfaces of the sample knitted fabric thus obtained, and the ratio was calculated by the following equation to determine the front and back area ratio of the water permeability and diffusion ability test.

Water Permeability, Diffusivity Test Front / Back Area Ratio = Diffusion Area of Front Surface / Diffusion Area of Back Surface When such a water-absorbent fabric is intensely sweating, it must immediately evaporate the sweat absorbed from the skin surface. In addition, the fabric itself reaches saturation due to the sweat that blows out without interruption. Therefore, it is necessary to add to the water-absorbing cloth-like material a performance for constantly maintaining the sweat-absorbing ability. In order to realize this practically, a breathable material having a large air layer and having a porosity of 50% or more is bonded to the back side of the cloth. By employing such a configuration, the amount of sweat transpiration can be greatly increased. By doing so, the water-absorbent fabric can maintain a state where it can always absorb new sweat without becoming saturated with sweat. Therefore, the sweat-absorbing cap of the present invention is capable of maintaining a refreshing sensation without bleeding into sweat, since the skin in contact is absorbed at the same time as sweating.

The present invention provides a continuous sweat-evaporation cycle, which cannot be achieved by such conventional techniques,
It is characterized in that the refreshing sensation due to the ability to constantly maintain the sweat absorbing ability can be maintained.

With respect to the material of such a water-absorbent fabric,
Polyester, polyamide, polypropylene, polyethylene, polyacrylonitrile, polyaramid, polycarbonate, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polyvinyl fluoride, which are hydrophobic materials
Stretched yarns, crimped yarns, and spun yarns of synthetic fibers such as polyvinylidene fluoride and polytetrafluoroethylene are preferable, but synthetic resinous materials and inorganic materials may be used.

The method of attaching the water-absorbent fabric is as follows.
The water-absorbent fabric itself may be configured as a single body as a head, or the air-permeable material 10 having a porosity of 50% or more may be used as a core material and attached to the core material. Further, in order to make them into a head band shape, they may be attached by stitching in a band shape or bonded by welding by heat fusion, ultrasonic wave, high frequency or the like.

The method of calculating the porosity of a gas-permeable material having a porosity of 50% or more according to the present invention means that a unit area of a porous sample is first taken, and a distance between each end face of the upper and lower surfaces of the sample is determined. The porosity is the volume ratio of air in the reference volume enclosed by these, and was calculated by the following equation.

Porosity (%) = (volume of air in reference volume / reference volume) × 100 As such a breathable material, a mesh having a coarse knitted leg and a relatively thick mesh is preferable from the viewpoint of air permeability. It is preferably used. However, an open mesh material is difficult to attach, and in order to improve this, a material provided with a band-shaped portion so as to enable sewing means is more preferably used. Further, in the case of a mesh material on a relatively fine flat surface, a mesh material having a thickness provided with irregularities on the mesh material itself, that is, having a relatively large air layer is preferably employed. As a means for providing such irregularities, a method such as pleating, corrugating, or spherical irregularity molding can be employed. As a particularly preferable material for such a breathable material, a double-raschel knit or a single-mesh knit having a three-dimensional structure is used. Further, a non-woven fabric or an open-cell foam is also preferably used. Further, in order to impart morphological stability, it is preferable to use a pleated or corrugated one in which the tops are adhesively connected with a flat fabric. Or, if the eyes are not fine, but if the mesh material with thick net legs,
At the intersection of the knitting legs, the thickness is equivalent to two knitting legs,
Since the gap is formed, it can be used by itself. In addition, as the above-mentioned double Russell knitted fabric, one having a honeycomb shape on the front and back surfaces and a shape having a thickness in a cross-sectional direction in which the front and back surfaces are connected by binding yarns is preferably used. The size of such a honeycomb-shaped hole is
The shape is not particularly limited, and may not necessarily be a honeycomb shape, and may be another shape, for example, another polygon. In this case, the positional relationship between the holes on the front and back may be in a position shifted from the front to the back, but it is preferable that the hole be located at the target position in consideration of the air permeability on the actual wearing surface.

In the case of a gas permeable material made of a nonwoven fabric, any method such as a needle punch method, a hydroentanglement method, a binder method, etc. may be used.
Furthermore, in the case of foam, it is necessary to be open cells, so those that are open cells at the time of foam molding, such as urethane foam, should be used as they are if only the skin part is removed However, those which are closed cells at the time of foam molding can be used in the same manner as long as they are pierced with a needle or pierced by post-processing to ensure air permeability.

On the other hand, as the aggregate, it is possible to apply the same material as the above-mentioned core material, but it is preferable to use a material which is more rigid than the core material. This is because rigidity is required because the function required for the aggregate is to provide the cap body with autonomy. The headband may be directly sewn to the aggregate for attachment to the aggregate, or one of the velcro tapes may be attached to the outside of the headband for attachment to the aggregate and the other to the aggregate. Mounting methods can also be used. As a feature in this case, since it is detachable, washing can be appropriately performed according to the dirt condition of the headband, and there is an effect that it can be used cleanly and comfortably.
Of course, if the interior material has a hammock shape, the same effect can be obtained even if the headband is attached in a hammock shape.

The material of the outer peripheral material of the headband portion is often restricted in appearance, especially in a hat, etc.
It is preferable to use a material having good air permeability.

Although a mesh material has been conventionally used as a material for the side surface portion, although a certain degree of air permeability is secured, steam escaping from the head cannot be used in a conventional structure.
It is extremely inefficient because it is only discharged through holes drilled in the aggregate. Therefore, it is effective to use an air-permeable material having a porosity of 50% or more as described above for the aggregate, even though the mesh material may be used as it is.

As for the ceiling portion, as in the case of the outer peripheral material, there is a restriction on appearance, but it is preferable to use a material having good air permeability as much as possible.

The conventional material for the top sheet of the water-blocking sheet is a laminated woven sheet of vinyl sheet and has no air permeability. As for the material of this part, it is preferable to use a water-absorbent cloth having the above-mentioned water permeability and diffusion ability test front / back area ratio of 1.0 or more. It is. In other words, by setting the surface having a large diffusion area on the side in contact with the head, even if the fabric absorbs sweat, the opposite surface has almost no wet feeling and does not stain the top fabric. In addition, with such a breathable material, since it is more breathable than a vinyl sheet with respect to steam, it is possible to provide a material that can obtain much more excellent comfort than conventional products.

The sweat-absorbing cap of the present invention means a covering structure for covering the head in order to protect from danger and protect from sunlight. Sports and leisure caps, helmets worn by SDF personnel and police officers during training and operations, helmets worn by postmen and crew members of transportation companies, helmets worn by workers at moving centers, and flying ,
General industrial helmet for falling. It is suitably used as a covering structure used in various fields, such as a helmet for a passenger car such as a motorcycle or an automobile, and a cap body worn continuously in a hot or summer environment.

When the cap of the present invention is worn under direct sunlight, it is more preferable that the shade fabric hangs down from the periphery of the cap. Further, it is preferable to use a cloth having water absorbency as a material of the awning cloth, because the sweat that has been sweated can be wiped off.

[0032]

The present invention will be described in more detail with reference to the following examples.

Example 1 Water Permeability and Diffusion Test Used for the Part of the Headband in Contact with the Skin A water-absorbent fabric having a front-to-back area ratio of 1.0 or more was produced as follows.

That is, using a double-sided circular knitting machine 22G, a polyester filament (100d-96f) is used as the knitting yarn 1 shown in FIG. 1, and a polyester filament (100d-1) thicker than the knitting yarn 1 is used as the knitting yarn 2.
Using 8f), a double-sided knitted fabric was knitted. The obtained double-sided knitted fabric was finished by ordinary scouring and dry heat setting.

The double raschel knitted fabric used for the core material of the headband was prepared under the following conditions. That is, polyester yarn (150 d
/ 48f), the binding yarn is a nylon filament (18
0d / 1f), using a Karl-Meier vertical knitting Russell machine, the course driving density was 22 stitches / inch, and the binding yarn had the same density, but the length was 4 mm and the honeycomb mesh was formed. did. This knitted fabric is dry heat 1
It was stretched and set at 80 ° C. for 30 seconds to develop a honeycomb structure. After that, a continuous pre-wetter machine was used to refine the oil removing agent to obtain a knitted fabric as a product.

The knitted fabric and the water-absorbent fabric were joined by regular sewing using polyester sewing thread.

As a starting aggregate for the side portion of the cap body, a net made of Nippon Netron Co., Ltd., product number NSK6, which is attached to a 30 mm wide, 0.5 mm thick band of the same material, is used. A belt-shaped portion cut into a width of 50 mm so as to be in the head circumferential direction was used, and the belt-shaped portion was attached by sewing. As the material of the side portion and the top portion, a commercially available fine mesh knit made of polyester was used.

Next, as the water-blocking sheet, the same product as the double Russell used as the core material was used, and the diffusion surface was set with the ceiling substrate side.

The cap thus obtained was put on, and the temperature was 32
A walking load was applied in an environment at a temperature of 65 ° C. and a relative humidity of 65%. The m / c used was a self-propelled jogging exerciser 28TT-8018 manufactured by Mizuno Corp., and self-propelled at a speed of 4 km / h for 20 minutes. Table 1 shows the results of the measured values obtained for each part after one hour.

Example 2 As a core material, Nisseki Sheet Pallet Co., product number OV7100
And a corrugating process was performed so as to have a thickness of 3 mm. However, a cap body was prepared in the same manner as in Example 1 except that the same material was attached only on one side.

The hat body thus obtained was put on, and
A similar walking test was performed. The results are shown in Table 1.

Comparative Example 1 In Example 1, as the sweat absorbing cloth for the headband part and the core material, synthetic leather of polyurethane film ("Kumus" manufactured by Daiichi Race Co., Ltd.) was used.

The aggregate was made of a 10-fold polyethylene foam having a thickness of 3 mm and a width of 50 mm, and the cap and the head were simultaneously attached by sewing.

The top material was a police summer uniform woven fabric, and the waterproof sheet was made of a 0.5 mm thick PVC foam, which was almost equivalent to a conventional hat.

The hat body thus obtained was put on, and
A similar walking test was performed. The results are shown in Table 1.

[0046]

[Table 1] As is clear from Table 1, the samples of Examples 1 and 2 did not feel any wet feeling in the head band portion of the head during the experiment, and when the inside of the head band was observed, the wet state was observed. Had not become.

On the other hand, the one of Comparative Example 1
After a lapse of time, the head portion of the head became sweaty and dripped. In addition, as for the feeling of wearing, the sweat flowed down as well as the discomfort due to the stuffiness inside the hat, and the eyes entered the mouth and felt unbearable pain.

[0048]

According to the present invention, it is possible to continuously evaporate sweat that is constantly sweating from the skin that is in close contact with the skin while absorbing it. Thus, it is possible to provide a cap body that does not cause sweatiness or stuffiness and does not cause discomfort.
